Two people were detained in connection with a possible explosive device found at Toronto’s Billy Bishop Airport Ferry Terminal October 21. The discovery prompted an evacuation of the airport. Operations at the airport were suspended. Toronto police said the two persons of interest were in custody and cooperating with the investigation. Officials at the airport notified police about a suspicious package at the ferry terminal on the mainland side. It was described as a potential explosive device, but according to Ports Toronto, which operates the airport, a “device” attached to a bicycle parked near the terminal was discovered. Police evacuated the ferry terminal and closed the pedestrian tunnel to the airport. The discovery of the device caused the closure of Billy Bishop Airport for the rest of the day. In a subsequent statement Saturday evening, the port authority said the incident led to two Air Canada flights diverting to Hamilton. They added that the runway had closed for the evening. “We’re doing our best to investigate that angle and learn what they know as quickly as we can,” said Acting Insp. Jason Albanese at the scene. Police tweeted that a controlled explosion was being conducted in the area and residents could hear a “loud bang.”
